I have an urethane super natural with a layout 30°x 3 3/4 x 30° and is OK for one or two games then start hooking too much and needs to start open the lines and don't really like that with an urethane bowling ball. I'll prefer to play straight.

I have another super natural ball undrilled, but wants to make it longer and strong back end, what kind of layout would you guys recommend ???????

Thanks Erick for you response, I will try as you said resurface both ball and also going to try the 1st layout to see how it works for me, Most of the time always have to play deep inside, but now I try something different that's why I come up with urethane.

I cant say I agree with that completely.The layout system should take into account the entire bowling ball as a design.There are adjustments for weak and strong coverstocks. Usually drill angle to compensate for length to 1st transition. If you'd like to weaken the reaction on the next ball you can try 50 x 4.25 x 45.

I could have worded that better.

The Sweetspot calculations are about the core.Layouts, from there, can be adjusted to accommodate different coverstock characteristics.

I still don't believe there is a need to adjust the Sweetspot calculations.
